Icelooks is a theme for IceWM that is heavily based on and looks very much like Clearlooks, the default theme for Gnome.
Or visit the sourceforge project page
To install the theme for your user, just untar the tarball in your ~/.icewm/themes directory (if you don't have one, you'll have to create it), restart icewm and select icelooks from the icewm themes menu.
For installing the theme system-wide, you'll have to untar icelooks in your /usr/share/icewm/themes directory. You'll need to have root user access to do that.
